6.6 Power supply (150 W)

Building Technologies
Fire Safety
The description for installing the power supply (150 W) applies to both versions of
the power supply, for the type A4 and for the type A5. Only the wiring of the
network connection and when switching in parallel are different.
With fire control panels in the Comfort housing, the power supply (150 W) FP2004-
A1 is always built-in. If you want to install an additional 150 W power supply
FP2005-A1 (optional), you must mount both power supplies in a vertical position.
When installing a power supply (150 W) in an additional empty housing, it can be
mounted horizontally on the DIN rail.
Primary wiring
WARNING
Electrical voltage
Electric shock
● Before connecting the mains cable, make sure that the cable is current-free.
● Ensure that the mains is secured against inadvertently being switched on.
Secondary wiring
NOTICE
Short-circuit
Damage to hardware
● Before removing or fitting the power supply, remove the jumper wire between
the two batteries.
 This ensures that the secondary side is current-free and that no components
can be damaged due to a short circuit.
EN 54-2 stipulates that the power supply must be installed in the housing.
The power supply (150 W) has an external temperature sensor. This must be
positioned directly next to the batteries.
